Absolutely terrifying. During Sunday's Winter X Games in Aspen, Jackson Strong attempted a back flip combo of some sort during the Snowmobile Freestyle event.But things went terribly wrong during the attempt and Strong flew off the sled. With the throttle still on after bailing, the snowmobile barreled full force toward the crowd when it hit the snow. Fortunately, the out-of-control sled was slowed by a crowd barrier, though it looks like it hit someone before coming to a halt.

Here's the video:

If you're familiar with the world of X Games, you know that Strong, an Australian, is an experienced motocross competitor. But then there's this:

Jackson strong only ever rode a snowmobile for 4 hours. So he enters the xgames. That's something @joenixbmx would do.

Glad the X Games have such rigorous qualifying standards. Where's the Lance Armstrong-esque outrage from the mainstream sports media?

@xgames its disgraceful to all involved u would let Jackson Strong compete. Resulting in an injured kid just #foolish @espn

Jackson Strong has no business even riding a dirt bike let alone a sled. He just proved why....
